Protect Your Knees at Any Age

knee-painKnee problems are the most common reason people visit an orthopaedic or sports medicine surgeon. May seem like common sense, but if you want healthy knees later in life, start taking care of them now, even if you are young.

The knee is the largest and strongest joint in your body and the major support structure of all your lower extremities. Unfortunately, as people age, knee issues become more common. Possible knee symptoms are aches, stiffness, and swelling and are usually caused by two main factors.

First, as we age, we lose some of the natural cartilage that acts as a cushion between the four bones in your knee joint. Damage to, or wearing down of, the cartilage causes pain and makes it hard to do many everyday activities, such as walking or climbing stairs.

Second, if you play sports, live an active lifestyle, or have suffered a knee injury, it is likely you may experience future or further knee problems as you continue to age.

Obesity has more recently become a major risk factor for knee conditions such as arthritis, not only of the knee, but also the hip and ankle.

Now that we know the major causes of knee problems, what’s a person with aging knees to do? While you can’t stop the aging process, you can follow these key tips to protect your knees.

1. Monitor changes in your knee health and record any signs and symptoms to share with your orthopaedic physician.

Symptoms from the aging process may be knee pain, but swelling is another common indicator. With age and cartilage loss, the body naturally responds by trying to repair itself, so there may be fluid in the knee, which is the body’s way of trying to increase shock absorption and lubrication in the knee.

2. Maintain a healthy weight

Every extra pound you put on places about four 4 extra pounds of pressure on your knees. Getting rid of extra weight may help alleviate knee pain or cure it altogether.

3. Exercise

Living an active lifestyle and incorporating low impact exercise into your routine promotes healthy knees. Make sure you leave enough time to properly warm up and stretch before starting your activity. Strength training uses resistance to build strong muscles and flexibility in the skeletal muscles.

4. Don’t overdo it!

Make sure you do not ignore the ongoing knee pain. If you play sports, consider additional training to learn proper techniques and alignment. When doing squats and lunges, don’t bend your leg beyond a 90-degree angle and make sure your knee stays directly over your foot. If injured, try using the RICE method to relieve immediate pain and reduce swelling: Rest, Ice, Compression and Elevation. And contact your healthcare provider if the pain persists or intensifies.

Takeaways from Dr. Bradbury’s Hip and Knee Replacements Chat

Thank you for participating in the online chat on Hip and Knee Replacements.  We had a lot of really great questions.  We received a few questions a couple times so we will highlight the answers to those questions here!

What is the longevity of knee replacements?

The lifespan of a knee replacement is related to the body weight and activity level of the individual who receives the replacement.  Individuals who are very active often reduce the longevity of their knee replacement because high activity can put extra stress on the implant leading to loosening of the implants from the bone or “wearing” of the parts used to replace the joint.  Being overweight increases the forces on implant and can also lead to early failure.  In general, 15 year survivorship of modern knee replacement designs used in  good candidate is around 90 percent.

Typically for younger patients,  if x-rays do not show complete loss of cartilage, “bone on bone”, I recommend waiting as long as possible to have the knee replacement surgery.  However, if there is “bone on bone” arthritis, knee replacement is the most effective treatment, but the risks of early failure are increased.

What exercises can I do for a total knee replacement?

Low impact aerobic conditioning 4-5 times per week for 4-6 weeks prior to surgery is best.  Low impact activities include swimming, elliptical, or stationary  bike.

“Prehabilitation” is rehabilitation to get your body ready for the surgery so you can recovery as quickly as possible after surgery.  Instruction during this period should be focused on strengthening the muscles around the joint.  The prehabilitation period should last for several weeks before surgery.

How long is recovery after hip/knee replacement?

It is best to think of how long it takes to reach recovery milestones –

• For hip replacement, pain is typically better than what it was prior to surgery in 2-3 weeks, normal walking typically occurs by 6-8 weeks and full recovery typically occurs within 3-4 months.

• For knee replacement, pain is typically better than what it was prior to surgery by 4-6 weeks, normal walking typically occurs by 8-10 weeks and full recovery typically occurs within 4-5 months.

Thank you again for attending the chat. I hope you found the information useful!  If you have questions or would like to schedule an appointment with an Emory Orthopedic Surgeon about hip or knee replacements please call 404-778-7777.
